Abstract
Jute seed production season, methods and related practices in terms of yield and economics were discussed reviewing the experimental results on jute in Bangladesh. The results revealed that jute seeds could be produced by traditional and improved methods. In traditional method (sown in March-April), some plants instead of harvesting for fiber is left in the field to continue reproductive growth. Whereas, in improved method (sown in the off-season) seeds are produced by direct seeding, top/stem cutting and seedling transplanting in the later season. The improved methods were found to be superior over the traditional. The traditional method had a longer field duration (240 to 270 days) than those of improved methods (120 to 160 days). The optimum time of off-season seed production was June-July for Corchorus capsularis L. while August-September for C. olitorius L. The average flowering days, pod maturation days and total field duration also depended significantly on the sowing/planting dates in the improved method. In the traditional method the seed yield of C. capsularis L. was 100-150 kg/ha; whereas, in C. olitorius L. it was 200-300 kg/ha which was remarkably lower than that of the improved methods (500-700 and 600-1000 kg/ha respectively). Pest and disease infestation was higher in traditional whereas, lower in improved methods. Higher net returns and as well as higher BCR (1.41 – 1.86) values were also obtained in improved methods.
